E I TANK COUPLING,

Application filed January 7, 1921. Serial No. 435,581..

To all whom it may concern:

Be it known that l, EMANUEL lvi. YOUNG- MAN, a citizen of the United States, and resident of the city and State of New York, in the United States of America, have invented certain new and useful improvements in Tank Couplings, described in the following specification and illustrated in the accompanying drawings, that form part of the same.

The principal objects of the invention are, to facilitate the work of connecting pipes to boilers, tanks, etc, for the installation of pipes connecting therewith by providing a coupling which may be inserted. from the outside through a. hole cut in the tank or boiler and clamped securely into place, and to devise a coupling of a very simple nature which may be easily, quickly and securely applied and which may be manufactured at a very low cost.

The principal feature of the invention consists in the novel construction. of a threaded member adapted to lit inside the boiler formed in two half sections hinged together and adapted to receive the coupling nipple and to clamp tightly against the inner surface of the boiler.

In the drawings, Figure l is a perspective view of my improved coupling shown in the position or being inserted through the hole out in the wall of the boiler, the wall being partly broken away at one side of thehole.

Figure 2 a. perspective view showing the coupling supported within the boiler immediately after its insertion the wall of the boiler being broken away.

Figure 3 is a perspective view of the coupling closed ready to receive the threaded nipple.

Figure 4 is a vertical sectional view showing the coupling assembled to the boiler.

Figure is a top plan view showing the coupling in place on the boiler which is shown in horizontal section.

The present invention has been devised to meet the requirements for a coupling which can be attached to boilers or tanks after they have been sealed in order to allow of the attachment of supplementary connections, such as the installation of water heaters where it is required to make a supplementary connection to the boiler or tank and it is therefore necessary for the coupling to be inserted through a hole bored: in the walloi the boiler. i

In order to accomplish. this result in. a simple manner-1 have devised, a coupling. formed in two half sections- The section 1 is siiibstantially semi-circular having a pair oi? parallelly arranged lugs 2 having porjecting portions 3 in which suitable pivot pins 4: are secured. The other semicircular member 5 is formed with flattened top and bottom surfaces 6 and 7 which lit between the inner sides of the lugs 2. i

The lug portions 8 are formed on the member 5 flush with the flat top and bottom surfaces and these are pivotally connected to the pivot pins i. so that the two members may swingso as to lie side by side in the position illustrated in Figures 1 and 2 or they may be swung to the position shown in v Figure 3 with the end surfaces of the member 5 abutting the shoulder surfaces 9 of the member 1.

-When the two members are thus arranged the inner threaded surface 10 forms a complete circle which is adapted to receive a threaded nipple 11. One of the pivot pins t is provided with a handle extension 12 which is bent at right angles to the pivot portion and extends through the threaded opening.

In placing this device in a boiler a hole 13 is :tirstcut the proper size to receive the threaded nipple 11. The hinged coupling member is then inserted in the manner shown in Figure 1, that is, one end of the two half circular members is inserted through the hole and it is then tipped through and it is supported by means of the handle member 12 in the position shown in Figure 2.

he two members are then swung upon the supporting pivot by inserting a finger through the hole and they are brought to the position shown in Figure 3. The threaded nipple 11 is then slipped-over the handle 12 and being inserted through the hole 13 it screwed in place in the inner threaded jointed member. Then the nipple thus inserted into the jointed member the threads lock the ointed member and it becomes prac tically a solid metal block.

The faces of the members 1 and 5 are curved to suit the interior of the boiler and fit snugly thereagainst. A gasket may be inserted if desired by slipping the same over the handle 12 and poking it through the hole in the boiler and a gasket 14 shaped to fit the outer Wall of the boiler is slipped over the handle 12 to :iit over the outer face of the boiler-and is engaged by the flange 15 of the nipple 11..

It will be readily seen that a device such as described is extremely simple. Itis easy to make and is Very easily and quickly installed and when installed forms an exceptionally secure connection. The nipple 11 is of course threaded internally to receive the necessary pipe connection and While it is not considered necessary to remove the 15 handle member 12 it maybe broken or cut ofl if desired after the nipple has been inserted.

Vhat I claim as my invention is A boiler coupling, comprising, a pair of substantially semi-circular nicn'ibers'a both of which are formed with abutting end surfaces and lug portions projecting from one side and having the interior threaded, a

pivot pin extending through one pair of said lug portions, a curved handle having a right angle bend, the end of which forms a pivot support for the members, and a threaded nipple adapted to be threaded into the inner threaded surface of said members EMANUEL M. YOUNGMAN.
